Dirt Bike Battery

When you’re ready to ride at the motocross track or on a scenic trail, nothing beats the convenience of a good battery that is ready to go. So if your battery is on the decline, make life easy again with a new dirt bike battery from Rocky Mountain ATV/MC. We carry a variety of dirt bike batteries to suit every style and budget.

We have traditional lead-acid batteries, lithium ion batteries and gel cell batteries. We carry leading brands like YUASA, Ballistic, Shorai, Antigravity, Bike Master and more. All you need to do is enter your bike’s make, model and year, and we’ll show you exactly which batteries will fit your motorcycle. (If you prefer to stick with the OEM battery, just click the OEM button at the top of the page.)

Even if your existing battery is still going strong, there are plenty of reasons to replace it with a better aftermarket one. For example, a maintenance-free battery can remove the headache (and risk) of continually checking and adjusting acid levels. And if you’re looking for a lightweight motocross battery, there’s nothing better than lithium ion! It’s one of the fastest (and cheapest) ways to shave a pound or two off of your motorcycle’s weight.

Tusk battery

bad experience

I've had this battery in the past in my 400ex and it worked great for many years however, I purchased it for my 700xx and had the same issue as a previous poster. I was able to charge it up and get it to start but it hasn't started since that day. When I put the tender on it I get a flashing red light which is an error code and it hasn't charged since. I appreciate rocky mountain's service dept. in taking care of my issue and issuing me an exchange for the one that didn't work. Hopefully the second one is a charm. Thank you Rocky Mountain for always being amazing to work with!

cold crank

works good, still seems to have trouble starting on COLD days. turns over fine, just not as good as a HARD kick. Never need charged. Very good battery, I was just expecting it to be 5 times the cranking power. Bottom line, always stays charged , even after sitting a long time. BAD-- it takes a special charger(not included) . I never bought one because it stays charged.
